Unabridged Note: Evidence from chloroplast DNA, morphology, and ecology was used by Fregonezi et al. [Taxon 61:120--130. 2012] to support segregation of Calibrachoa from Petunia, as well as recognition of Calibrachoa parviflora (Juss.) D'Arcy, which was said to occur "in North America and Europe, probably as a result of introduction from South America and subsequent naturalization".Jepson eFlora Author: Michael H. Nee
